Solving Common Problems
The unit has detected too
important polarization
fluctuations on the fiber. No
PMD measurement was
performed.
³ The unit was moved
during the
measurement
³ The fiber moved during
the measurement
³ Make sure not to move
the unit.
³ Make sure that the fiber
does not move during
the measurement.
³ If some movement is
inevitable (fiber is
outside with aerial
sections), make sure
that the Fiber with
aerial sections option is
selected in the Setup
tab of the Acquisition
window.
³ Contact EXFO if the
problem is still not
solved.
